My favorite antenna tubing source is Texas Towers. .058" wall tubing from
.375" through 2.125" OD is available in 6' lengths for UPS shipping or 12'
lengths for truck freight. Truck shipping is obscenely expensive for small
quantities.
I also use Online Metals for custom lengths and their vast selection of
materials and shapes.

DX Engineering sells 0.058" wall tube up to 1.5" od. Onlinemetals.com is
now carrying 0.058" wall to 2" and sells in 1' increments to 8' (as well
as many other od/id combinations). I think with these sources you can
find what is needed to replace and sleeve where needed.
I internally sleeved the boom ends and replaced and sleeved element
clamp areas on my CC A4S. Field Day assemblers have been too
enthusiastic in tightening things.

Since Cushcraft/MFJ does not actually make this version anymore, how do I
get parts for it? I have looked and compared the 40-2CD manual and the
XM-240 manual side by side, and the end boom sections are different diameters.
Would buying the XM-240 end boom section and the 12" long coupler work?
